Trike....sit in traffic jams in the rain for perhaps a smile or two...
Sorry but a bike makes sense, one simply goes through the traffic, and one comes out the end of the jam often wondering what the jam was about but anyhow, the point is if you're going to get rained-on and frozen it might as well be useful in the traffic, if not get a roof and heater [-/ eg a 126

Yes I guess the sun comes out and it could be fun...sunroof would be better than fiddling between one's legs

The only advantages I can see is the wife sits a bit further away than on a bike making it harder for her to dig her nails into one's side when she disapproves of ones driving...
One disadvantage is one doesn't need to wear a helmet on a trike....the peace and quiet of a helmet...would be missed
